Where are you located in AZ? I'm in Surprise. I'd love to hear how a properly set up system sounds.

You can dial it in using a calibrated spl meter and test tones. It takes a bit of time. Or you can go the direction of REW and a laptop to measure the sub(s) and calibrate it that way.

I've been happy calibrating each position using an spl meter. In my findings, my results have been much better then letting ypao do it. You can also unplug the sub, run ypao, then calibrate the sub by itself.

If I could sell my 3010 for a fair price, it would immediately be replaced by a Denon 4311ci because of audyssey and having the ability to upgrade it to pro. As it stands right now, I'm happy with my manual calibration. I'll look at replacing it next year or whenever the next level of audyssey hits in the Denon top tier line. I love Yamaha but charging the same price as a 4311 and using ypao instead of audyssey irks me. My opinion would be different if Yamaha would strive to update ypao on a constant basis and fix its short comings.

So I am off for the next four days and am going to do my best to dial in the V15h. I also just got an Onkyo 809 (replacing an Onkyo NR901) so I will be setting that up as well. In addition, because of the capabilities of the 809, I will also be adding front heights (cannot do rear surround as you will see).

Dr. Hsu - can you give me some initial thoughts/suggestions about my layout and positioning of the V15? I have attached a pic of my room and I apologize for its lameness.

I will make a couple notes about it. First, the TV is actually on a long Ikea console so, although I could put the sub in either of the front corners, that would cause me to permanently have my Aperion VGTs out in the room which my wife has nixed. I usually move the speakers out during movies and then move them back again for regular TV viewing.

The open kitchen is the same distance front to back (like the TV to couch distance), but is about 17 feet long. 8' ceilings all around. There is a large island in the middle of the kitchen.

As a result of the above, the only two spots for the sub are on either side of the couch unless I am missing something.

Does it matter which way the sub is "pointing" (back toward the fireplace wall or window wall? What settings should I start with prior to the calibration process? I do have an RS SPL and plan on setting up and using REW.

Thanks for any suggestions from the group as well!

Listening postion or both that you're referring to? I'll probably do both to see what I'm actually getting out of the subs 2M at first then listening position for comparision.

I hate to turn this into a YPAO tutorial but maybe this will be good for HSU when they troubleshoot and ask the customer "What amp brand and are you running YPAO"?

Thanks for the help and all the knowledge, my head is spinning haha! I'll get there, hopefully just sooner then later

I don't believe the 667 has it, so modifying the subwoofer's frequency response will need to be done off-board.

I mentioned this to someone in a private message. You gotta get your hands on a SPL meter to see the whole picture and know what your frequency response curve really looks like. Radio Shack's digital SPL is fairly inexpensive and does a reasonable job.

If you really want to road trip it to Tucson, let me know. The I-10 is a horrible drive. haha.

I also like to see the in-room responses with the mic at ear level at your listening position, with the two subs at your current location, and with the 15H between the two sofas. Try two ports open, EQ2, Q=0.3 for in-room (if you feel energetic, do it for 1 port open,EQ1, Q=0.7 as well).

When I calibrate with a meter, I wear hearing protection. Reference level for calibration is really 85db but can damage hearing. So most of the avr's out there do the testing at 75db. Make sure you purchase a popular spl meter that has a calibration database such as the radio shack. All of the information can be found here on AVS with a quick search. Below I'll supply you a link on how to calibrate your speakers manually as a guide.

Tell your wife the 15H is defective and you need to send it back for a replacement. Hide the 15H and ship the dogs in the 15H box to Dr Hsu, who in turn will send you another 15H. Problem solved!

Of course since I'm divorced, I would lean towards shipping both the wife and the dogs to Dr Hsu.

Also was it supposed to come with a disc??
I can barely hear it at the moment

Tomorrow night is "War Horse" on Blu-Ray. From what I have gathered it is reference material....

Will let you know

So, i'm still ify on phase and crossover?
I have ypao so I guess i'm tuning manually. I only used ypao for speakers, than turned sub back on.

Should I set out or in and what, to 90?

And the phase , I can't tell which is better

Confused...
Also i'm tuning to music at the moment because we're having a party in a few hours!!

The other thing.. All the low freq test tones have me literally feeling sick to my stomach...

I would set crossover on the sub to 'out'. Frequency does not matter once you set crossover to 'out'. If you set the crossover on the Yamaha to 80 Hz, sit in your listening chair, play 80 Hz tone on our CD, and have someone flip between 0 and 180. Whichever position sounds louder is the position you want to keep it at.

Later, after the party, you can adjust the distance parameter for the sub and use a SPL meter to see what distance setting gives you the highest output at 80 Hz (SPL meter at ear level at your listening chair). That would be fine tuning for the best phase matching between the sub and your main speakers.

Yes, the army should buy lots of 15Hs and blast the enemy to make them sick!
